Anzrnscrseis'Ln'1 WRITING IMPLEMENT Application' inea october 22,1930. serial No. 490,478.'

" AMy invention relates to adjustable writing implementsl in which one or two colored leads may beemployed.

A purpose' of my invention is to provide a two color writingv implement `in `'which standard leads may be employed 'for ini-- mediate selectiveuse, that is, by turning the cap end of the pencil in one direction to feed forwardly one lead, or in the opposite direction to feed forwardly another lead.

A further purposeA is to fasten a spr-ing pocket clip 'to' the out the use of rivets or the like.

A` further purpose is to feedthe different leads by an integrallyfthreaded sleeve, the

upper half of the sleeve being threaded in one `direction and the lowerV half being threaded inan opposite direction.

A furtherV purpose is to provide a tracked guide wit in the threaded sleeve port the feed rods of `leadholders A further purpose is to provide the feed rods with outwardly directed spring-pressed fingers adapted to ride in the groove in the sleeve.V l f U 4 A further purpose Vis to apply spring pressure to av cap-receiving ferrule -to take up wear at the top `of the body portionf of the pencil.

A further purpose is to place a holder for spare leads near the point of the pencil.

A further purpose is. to provide an internally grooved the tip of the pencil.

` A further purpose is to provide a two color pencil that is easy of manufacture and simple in construction and which well meets the needs of service. v Further purposes will appear in the specifcation and 4in the claims.

I have elected `to show one only ofthe different forms of myr invention, selecting however a form that is practical and effi@ cient in operation and which well illustrates the principles involved.l

tation and referring to the drawing l i`654 My vpencil is particularlyv welll adapted*- for use when two colors are desired but has n another advantage in that twoleads of the Y doublel same colormay befin'sertedfor use and one lead may be used as lan auxiliaryl lead.

Twoleads havebeen, used before in pencils, but to the best of my -lmowledge I am the first to use a pencilthat'byturning a portion thereof in either of two ,directionsm different standard leads may be brought into writing position.

My pencil comprises a tubular casing 10 bored at 11 and'counte'rbored at l"12.1 `A sleeve 13 is fixed in: the bore 11 and a maga-V zine 14 for leads is inserted into the counter-V bore 12. V y f t A hollow spacer 15 is fixed above and supported on f the sleeve 13 and 'registers-V flush .with the upper end 16 ofthe tubular rotatably mounted within the upper en d of the spacer 15V with'whichits downwardly projecting Yhollow extension 18 engages.

This extension 18 acts as aterminal for.` and is connected to rotate with the ,upper end ofY a Acontinuously grooved sleeve 19. Thesleevemaybe soldered to it and atits upper end extends at 20 into the hollow of the top 17; 'The hollowing of the top forms a ferrule 21. V' Y e [A double-track Yguide V22 is mounted in 1 side the grooved sleeve 19and 'at its bot-Y tom`j23 registers vwith thebotto'm 24 of the lead holder 14. i Atits top the guide 22 ex- Y ff carries twooutwardly extending projections V which may be integral with the guide 22 low ofthe .top 17, I place aspiral spring 28,

which is 'centered at its bottom about the projection 2O of the grooved sleeve 19.

CItwillbe evident that the errule 2l resiliently pressed. by the spring 28 againstl theinner and end surfaces of the spacer 15.

' The guiding sleeve 19 is iirmly held inthe ferrule'. In this way the sleeve 28, provides a brake action, vtending to'maintain the' sleeve T19 in any angular position in which it is set, and preventing.,shitting ofthe setting r`of the roperative lead holder during use 1 diameter of the pencil. between the ferrule and the hollow spacer 15 occurs over a relativelywide surface so that the spring 2 8 vneed not be of heavy construction. n

. At its lower end the Aguide 22 is split to form two outwardl* extendinon ro ections .y s p 29 that t into vertical slots 30 in the pro-A jecting end 310i the lead magazine. 14 fto firmly hold the sleeve 19 in )lace between the upper and lower ends of the pencil.

This structureabove the top of thefbody 10 is enclosed by a top capV 33 heldin place about the ferrule21. g The upper A.end of the cupV is vertically slotted at 17"for the doubl'epurpose of allowing frictiona'l" engagement with the cap 32 and resiiiently holding the rubber. Y

' The walls of' lead magazine 14 extend downwardly at 34 and are ribbed atY 35. In order to permit use of a casing of smaller than could otherwise be used, the

Y thread '3G is interrupted torallow for sin# sertion of' spare leads-in the spaces 87 in themagazin Vg At its Yupper end theholder terminates in a iiange 14 `fitting the counterbore 15 andat its top engagingthe bottom of the inner sleeve 13. The leads at their inner ends rest against the ilange 14 and at their outer endsY against the threaded washer39.V A hollow tapered tip 38 carries a threaded washer 39. The tip is spun into or otherwise locked about the washer as'seen at4() the thread 36 of the lead magazine 14;

The washer 39, being securely held in place, acts. as aY Vsupport for. the leads in the magazine 14 when the tipY 38 is in place on the pencil. l

and Ythe tip 41 as a Whole is threaded uponv .An important feature of my inventionis the construction ofthe leadfeeding mech; anism, which:comprisesthe sleeve 19, Vguide 2.2and sjniingfjaiessecl lead carriers 42 andV j a much Y j n p the center of the sleeve, whereV at kT47 ythe VThe y'frictional engagementV n n socket, the spring action Above the washer 2G in the terrule 21Y I insert an eraser v82 otrubber `or the like.

The sleeve 19 is provided with,y relatively reversed internal spiral guiding grooves 44 which may be and, as illustrated, are, con-1 vIn the best form known to vme this vspiral Y track starts at its upper end withl a number of turns 45 of slight pitch, it then assumes greater pitch at 46 until reaching spiral is reversed in directionforanumber of turns at 48. at a slight pitch and then assumes a greater pitch at 49 in the changed direction. The twooperating feed grooves 47 and 49 are thus Iof preterably the same pitch' but in the oppositejdirection. The lower groove extends tothe endo'f the sleeve;`

The lead carriers 42 and 43 atftheirl upper ends present spring fingers 5() andl; which press resiliently against the bottom of the spiral groove, the finger 50 riding in Athe upper half (groove portions 46 and'47)rot 57 in the sockets, ybut the sockets 'cannothe' come detached from the carriers. Y Near the top of the pencil I apply a clip 58, `bent laterally vat projection V60 and, for, economy of space, an

y the sleeve 19 and the finger 51 riding in the lower half (groove lportionsj48 and Y l49) 90 f 59 with a downward"v inset portion in the form of a notch 61;

Whether this be inset or not, the lower end carries a lateral projection 62 fitting into the interior of the. body 310 throughv a slotY G3 in the body. n

The intermediate shank rests in a vertical groove 64 in the side of the (inset tportionl spacer lfand the lateral projection 62 fits f into a slot 65,v engages the bottom of the inner sleeve tov hold the clip in'place., Itl

will be obvious that the clip is securely held in place to the pencil without rivets 0r other fastening means which would tend to break lor split the casing or body.r

When lead is to be inserted the operator removes the tip thus making the leads Within the lead holder accessibleso that one of them Vcan be removed. I-Ie then screws out the lead carrier bringing the socket .Within easy reach, pushes the socket back' to discharge any'stub'of used lead and inserts the'lead into the socket. J f

which may be intherei and subsequentlyL pulls the Vsocket forward imager 'j-or'if it Vhas `beenfremoved tb ive access to the rubber, the cuppedxmem er lel-f-is turned inione direction to'project one of tlieleads ,or in the opposite direction to pro,- ject the other of the leads. Infeitherfcase the projection of one"automatically withdraws theother.` L y l u,

It 4will be V-evident that the spring rmeme bers 50 and`5l not Vonly insure smoothY and reliable .engagement with the internal grooves to move. the-leadacarriers forward and l.backbut clean the interior ofthe thread paths ofburs or otherfobstacles `or rideyover these obstacles when they :are not readily removed. v i. `It will be clearlyseen that my pencil has an approximately direct linelead feed due to the arrangement Iof the lead earrierlba'rs in the sleeve.

The sockets at the ends of the lead carrier bars,'allow Vfor slight resilient movementof the" leads which is necessary on-account of the slight converging of tlielleads` as-they are projected through the' tipof thel pencil.

This angular movement ofthe lead, being veryslight, allows the lead to-l be presented through the tip. of thep'encil atanV angle-that l r f opposite directioni'a'nd 'a1 tapered ti`pdirectl Y ing @andasupportingoneof vvthe' leads at 'a'V i. 1 1p-95V... v
